ER2000 Electronic Controller

ER2000 Electronic Controller

2183

The Clorius ER 2000 electronic controller is used for constant temperature control. It is suitable for all heating and cooling control systems. The controller is primarily intended for marine installations and other industrial applications – such as cooling water and lubricating oil installations, flow temperature control etc. Design The ER 2000 controller is designed for panel mounting. For an easy start-up, it has optimization for the automatic determination of favourable control parameters. The optimization starts when changing the set point or when switching over from manual mode to automatic control. The optimization can be disregarded. For easy operation, it has three keys – two for scrolling or changing values and an enter key. Two digital displays show the process variable and the setpoint. 3 LEDs indicate actuator opens, actuator closes and alarm. The controller can be switched from auto mode to manual mode. In manual mode, the actuator can be opened, closed or stopped in a certain position. Three different alarm settings are possible: Alarm at a deviation from the setpoint SP Alarm at a fixed limit value Alarm at leaving a band around the setpoint SP It can operate either as a three-position or as a two-position controller or analogue (4-20 mA) controller and has an adjustable proportional band, integral action time and derivative action time. Function The temperature input comes via a Pt 100 sensor with a single sensing element. The measured value of the controlled variable is compared with the setpoint value and adjusted via a PI or a PID control structure. The ER 2000 can act as either a heating controller, the actuator closes at rising temperature, or as a cooling controller, the actuator opens at rising temperature. The ER 2000 permits direct reading of the actual temperature value (PV), and it is secured from failure in the measuring circuit, i.e. the controller can be set to give either a closing, an opening, or remain in current position command in case of sensor short circuit or sensor break. The error message Err appears in the LED display PV.

H3F 3-way Control Valve

H3F 3-way Control Valve

9083

The Clorius H3F 3-way control valve is designed for control of hot oil, water and other liquids and can be installed in pipe systems as mixing or diverting valves. The H3F control valve is used in conjunction with Clorius temperature regulators for controlling industrial processes, district or central heating plants or marine installations. The valve components – spindle, seats and cone – are made of stainless steel. The valve body is made of cast steel GP240GH (GS-C25) with flanges drilled according to EN 1092-1. The thread for the actuator connection is G1B ISO 228. The valves have two balanced single seats. The leakage rate is less than 0.5% of the full flow (according to VDI/VDE 2174). Without an actuator being installed, connection A-AB is fully open and connection B-AB completely closed, by means of a spring. By increasing pressure on the spindle, the opening of the ports changes proportionally to the travel of the spindle, and when the spindle is pressed to the bottom, connection B-AB is fully open and connection A-AB completely closed. The valve characteristics are as follows: Port A-AB and AB-A: quadratic Port B-AB and AB-B: almost linear These characteristics ensure constant total flow under almost all pressure conditions and optimum circulation in the individual circuits.

The Clorius M3F 3-way control valves are designed for lubricants, hot water and other liquids and can be installed in pipe systems as mixing or diverting valves. The M3F control valve is used in conjunction with temperature regulators for controlling industrial processes, district or central heating plants or marine installations. The valve components – seats, cone and stem are made of stainless steel. The valve body is made of cast iron EN-GJS-400 -15 with flanges drilled according to EN 1092-2 PN 16. The thread for the actuator connection is G1B ISO 228. The valves have two balanced single seats. The leakage rate is less than 0.5 % of the full flow (according to VDI/VDE 2174). Without an actuator being installed, connection A-AB is fully open and the connection B-AB completely closed by means of a spring. By increasing pressure on the spindle, the opening of the ports changes proportionally to the travel of the spindle, and when the spindle is pres sed to the bottom, connection B-AB is fully open and connection A-AB completely closed. The valve characteristics are as follows: Port A-AB and AB-A: quadratic Port B-AB and AB-B: almost linear These characteristics ensure constant total flow under almost all pressure conditions and optimum circulation in the individual circuits.

L3FM-T 3-way Control Valve

L3FM-T 3-way Control Valve

9105

The Clorius L3FM-T is a three-way control valve with a slide for a quarter-turn operation designed for regulating seawater. The L3FM-T 3-way control valve is designed for use in conjunction with valve motor type CAR with handle for manual operation or for use in conjunction with a pneumatic actuator. The valve body is made of gunmetal, while the slide is made of alu bronze. The valve flanges are drilled according to EN 1092-2. The slide is firmly connected with the actuator spindle. When the slide is in the one extreme position by turning the spindle, connection A-AB is kept fully open and connection B-AB is fully closed. In the other extreme position connection A-AB is fully closed and connection B-AB is fully open. In the intermediate positions, the opening degrees change proportionally. The valve has a small tolerance between the body and slide. To minimize the leakage an O-ring is mounted in a groove on the slide.

9113

The Clorius G3FM-TR 3-way control valve with a slide for a quarter-turn operation designed for regulating freshwater, lubricating oil and other liquid media. The G3FM-TR valve is designed for use in conjunction with industrial processes, district heating and marine installations with large water or lubricating oil volumes: Engine Jacket Cooling Water System Lubricating Oil Cooling Central Cooling Water System, etc. The valves are designed for use in conjunction with valve motor type CAR to handle manual operation or use in conjunction with a pneumatic actuator. The valve body and the valve slide are made of nodular cast iron. The valve flanges are drilled according to EN 1092-2 (JIS B 2210 option). The slide is firmly connected with the motor spindle. When the slide is in the one outer position by turning the spindle, connection A-AB is fully open and connection B-AB is fully closed. In the other outer position, connection A-AB is fully closed, and connection B-AB is fully open. In the intermediate positions, the opening degrees change proportionally.

The Clorius ER 3000e electric controller is used for constant temperature control. It is specially designed for large engine jacket cooling water systems where conventional single loop controllers cannot maintain a constant and precise temperature. The ER3000 controller operates with TWO sensor inputs. One Pt 100 sensor is placed at the outlet from the engine and one Pt 100 sensor with a built-in 4-20 mA transmitter is placed at the inlet to the engine. The measured values of the controlled variables are compared with the setpoint value and adjusted via a PI or a PID control structure. Design The ER 3000 controller is designed for panel mounting. For an easy start-up, it has optimization for the automatic determination of favourable control parameters. The optimization starts when changing the set point or when switching over from manual mode to automatic control. The optimization can be disregarded.
